Same story as with 0.6.3 and 0.6.4, again we're doing a release to fix a vulnerability. If you're actively playing Teeworlds, you likely already noticed that a lot of servers were full of "(connecting)" clients. This was possible because you could forge the connection packet in a way that made it seem like it came from an arbitrary IP address.

Other than that, the release is mostly technical, allowing to build Teeworlds with the popular CMake build system and fixing a build error with gcc. Additionally, the initial connection handshake turned out to be unnecessarily slow: The client waited 500ms before sending the initial info for player name, clan, tee color, etc.

Go download it now!

It looks like the 0.7.0 release is also coming closer, so maybe this release will have a short lifespan.
